BURR EASTWOOD, OF

FLUSHlNG-TANK.

Specification of Letters Patent.

Patented Aug. 7, 1906.

Application filed January 19, 1905. Serial No. 241,829.

To all whom it may concern:

Be it known that I, BURR EASTWOOD, a

citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Flushing-Tanks, of which the following is a specification.

M invention relates to tanks for flushing bow s and basins, and has more particular reference to the construction, supporting, and operation of the valve which permits the water to escape from the tank into the bowl.

3 An embodiment of my invention is shown in the accompanying drawings, in which- Figure 1 is a sectional elevation of a tank containing my improvements. Fig. 2 is a cross-section of the same. Fig. 3 is an enlarged sectional elevation of the valve and associated parts. Fig. 4 is a side elevation of the same. Fig.5 is a plan view of the valveseat.

The tank 1 may be either an elevated tank or of the low and accessible kind. It is shown as of the latter character, and the flushing is controlled by the push-rod 2. This rod is guided on the outside of the tank and is connected through a slot in the wall with a rod 3, working between the tank-wall and its inner lining 4, as shown in Fi 2. The rod 3 is connected to the pivotedfiever 5, having the chain 6 attached tothe valve-rod 7. The inlet-pi e for water is shown at 8, with the usual li t-valve 9, controlled by the ball-float 11. In the position of Fig. 1 the tank is full and the float 11 throu h its hinged rod 12 and stop113 is keeping t e water-inlet closed. When t e button is depressed, the main outlet-valve is raised, ermitting the water inough the flushing-pipe the tank to escape t is connected into the 14, which, of course,

. bowl.

' packing the valve is shown but the details The construction of throughout the drawings, thereof are best illustrated in Fi s. 3 and 4. The exit-pipe 14 is coupled to t e tube 15, which is formed with the inclined valve-seat through the bottom of the tank. The valve-plate has a deep groove for two flanges 18 19, between which is set t e rubber packing 21, which makes the actual closure. upper flange .8 is made wider than the inner diameter of the tube, so that a valve accidentally disconnected or which has lost its cannot fall into the exit-pipe. The

wear and concussion between the va valve-rod, lockin Preferably the tube has a flan e 22, which rests upon a rubber ring 23 on t e bottom of the tank. A nut 24, threaded on the tube outside the tank, keeps this ring compressed and makes a tight joint. The upper end of the tube is formed with rojecting lugs 25 and with strengthening-ri s 26. ecured to the valve-seat and resting directly upon the lugs 25 is a bracket 20, which is preferably-formed in the shape of an arch, as shown. This bracket has a central vertical guide 27 for the valve-stem 7 and is provided with a horizontal intersecting passage 29. The valve-rod is threaded into the valve-plate and is preferably provided with a rubber cushion 31 to revent ve and the guide 27. In the passage 29 works a bolt 32, which is jointed to a rod 33, pivoted on the bracket. The free end of this rod carries a float 34. I prefer to use a disk of cork slipped upon the rod and held between clamping-plates, and in order to give the cork disk greater wearing quality I boil such disks thoroughly in para without aflecting the buoyancy. The usual hollow floats-of copper or zinc seamed and soldered are liable to be aflected by the water and to leak. Hence I refer the cork float shown, although any 0t er float can be used instead.

.With water in the tank the buoyancy of float 34 keeps the bolt 32 up against the valve-stem. This stem has a groove 35 with which said bolt is adapted to engage when the valve is lifted, the operation being as follows: Taking the apparatus in the position of Fig. 1, with the tank full, the chain connected to the valve-rod is pulled by depressing the push-button, or, in elevated tanks, by pullin the ordinary outside chain. This lifts t e valve and permits the water to escape and flush the bowl. When the valve lifts, the bolt 32 enters the groove 35 in the said rod and holding the valve up until al the water has run out. When this has taken place, the float 34 drops by its own gravity and withdraws the bolt from the groove, permitting the valve to close again.- The Water inlet has been opened by the descent of the ball 11, permitting the tank to refill.

It will be noticed Hence the action of the valve is always posiflin, which fills the pores that the valve-rod is, I guided in a long hearing, which is always 1nwhat I claim as new, and desire tive and it cannot be diverted from its proper line of motion relatively to its seat.

I have shown at 36 the usual overflowpipe communicating with the water below the valve through a port 37.

I do not limit myself to the specific details of construction and arrangement herein described, and shown in the drawings, as I desireto avail myself of such modifications and eguivalents as fall properly within the spirit 0 my invention.

Having thus fully described, my invention, to secure by Letters Patent, is

In a flushing-tank, a discharge-pipe hav ing an inclined valve-seat, a bracket secured to the seat and having a long 'de-sleeve above said seat, a stem passing t ough said guide and having a roove therein, a valvedisk secured to the ower end of said stern, said disk having an upper and a lower circum ferential fiange the up er flange being of reater diameter than t e diameter of the ischarge-pipe, an annular disk of rubber held between the flanges, a passage'intersecting the bore of the guide-sleeve, a bolt sliding in said passage, an arm jointed to said bolt and a float secured to said arm.

a In testimony whereof I have afii'xed my signature, in v resence of two' witnesses, this 13th day of ctober, 1904.

BURR EASTWOOD.
